1.15. Auxiliary Feedback (Bi-Directional)
When using one of the Auxiliary Feedback options, the relevant functionality of the Auxiliary
Feedback's ports are software selected for that option. Refer to the SimplIQ Command
Reference Manual for detailed information about Auxiliary Feedback setup.
The Auxiliary Feedback connector has two ports: B1 and B2.
 Port B1 has three pairs of differential buffered inputs
 Port B2 has three pairs of differential buffered outputs
There are two modes of operation for this interface:
 Mode 1 (Composer Command: YA[4]=4) – see Section 1.15.2
When the Auxiliary port of the Solo Guitar Absolute Feedback is set by the software to
act as an output
 B1 input becomes inactive
 B2 presents differential buffered encoder output signals of the Main Feedback
 Mode 2 (Composer Command: YA[4]=2 or YA[4]=0) – see Sections 1.15.3 and 1.15.4
When the Auxiliary port of the Solo Guitar Absolute Feedback is set by software to act
as an input
 B1 becomes an active differential buffered input
 B2 presents differential buffered encoder output signals of B1
